Matt,
Signals do change as you change height as you expose or conceal
the even number Fresnel zones.
Thank You,

Can you explain this more? This isn't what I was getting at... but
since you brought it up and it's been brought up before it might be
worth explaining in more detail. I'm familiar with the concept but
still can't grasp why it works.

What he wants, is, here is my customer location, how HIGH do I need to go
to get an acceptable signal. If you are going though trees or near a hill,
the Fresnel zones include constructive and nonconstructive zones.
sometimes going up 5 feet may help and sometimes it would harm. These are
only
Right. That makes sense. There are some that say that even with a clean fresnel
going up or down 10 feet can change things. Never understood that.

I've seen it before too. On the ground with a nanobridge 5 feet above the
ground with me holding it, I can get a -58 but go up 10 feet on the roof
and it's a -63 with same aiming and clear LOS. Bugs the heck out of me. But
I'm not able to go even higher in some cases to try to get a -58 back and
Fresnel zones are 180 degrees out of phase with even and odd numbered zones
(1st, 2nd, 3rd and so on). When you design a path you strive for an exposed
Fresnel zone of between 1 and .6 of the first zone, meaning you use the
ground/trees/obstructions to block the second and higher numbered zones
Interesting explanation. Thanks.

The other thing that changing height can do is change the angle of
reflected/refracted signals thus changing the amount of multi-path
signal the receiver sees.

Yes, good way to look at it Brian, thanks.
So, is there a minimum height per frequency... say for 900Mhz you should
never shoot less then x feet', like less then 6'?

Still needs more testing before it goes live.
Is it sad that I was ecstatic to see that?! Love it when the shop tests
before deployment.

Ok, Ya'll win. The programmers are working on this as we speak.
Finding the needed height for the desired signal is going to be
automatic. The site is going to look at the desired signal. If it is
below what it should be the it is going to start raising the antenna
until the desired signal is
Sweet!!!

Not really, Fresnel zone size is a function of frequency and distance between
the two end points. The zone is football shaped with the widest part of the
zone half way between the two end points. Antenna patterns have nothing to do
with Fresnel zone size.
Here is a Fresnel Zone size
Excellent!
